n: on an engine, a device that contains an air filter element that does not depend on oil to effectively filter the air entering the engine. Instead, the filter element has a number of folds and chambers that bap dust and dirt going into the engines air intake. Some dry elements may be cleaned and reinstalled;others are discarded and replaced. Compare wet air cleane1:

n: a special compressor used on two-stroke engines to supercharge the engines intake air and scavenge (remove) exhaust gases from the engine cylinders. The blower has tWo corkscrew-shaped (helical) rotors with blades (lobes) that rotate inside a housing. The engine drives the rotors with gears at about twice the engines speed. The rotors rotate in opposite directions at the same speed. As they rotate, the lobes compress air drawn through an air cleaner on top of the housing. The compressed air exits the blower from the bottom or the side of the housing and goes into the engines air intake manifold.
